Filed: 1986-03-06
Abstract: PURPOSE:To avoid the effect of temperature increase in a semiconductor-element fixing process, by independently forming a lead frame forming part other than a pad part and said pad part, and making it possible to couple both parts. CONSTITUTION:A pad part 20a and a lead-frame forming part 20b other than the pad part are independently formed by blanking or etching. Protruded parts 26a are formed on supporting bars 26 and recess parts 25a are formed in frame bodies 25, so that the pad part 20a and the lead frame forming part 20b are coupled. Under the state the pad part 20a is disengaged from the lead frame forming part 20b, a semiconductor element is fixed to pads 21. The pad part 20a, to which the semiconductor element is fixed, is fitted to the lead-frame forming part 20b. Thus the effect of heat, which is yielded when the semiconductor element is fixed, can be avoided, and the highly reliable semiconductor device can be obtained.

Title: Safety device at extinction of gas appliance
Inventor: MORI KEIICHI
IPC: F23N5/02
Filed: 1983-03-23
Abstract: PURPOSE:To obtain a safety device at flame failure, which necessitates no high accuracy of finishing and yet has high safety and quick response time, by a structure wherein a ball valve is opened and closed by the change of the shape of a flame detecting part consisting of shape memory alloy. CONSTITUTION:At the misfiring or flame failure of a burner 12, a ball valve 13 closely contacts with a valve port 16, resulting in preventing gas from flowing from an inlet 14 to an outlet 15. Under the condition that the burner 12 is burning, a detecting part 9 is heated by flame 1 and consequently changes its shape so as to move a working rod 11 in the direction of arrow A. Accordingly, the ball valve 13 is pushed so as to open the valve port 16, resulting in flowing gas therethrough. Thus, a safety device at flame failure, which necessitates no high accuracy of finishing and yet has high safety and quick response time, can be obtained.

Title: Parametric speaker
Inventor: TANAKA TSUNEO
IPC: H04R3/00
Filed: 1987-03-04
Abstract: PURPOSE:To prevent an amplifier from being broken and to use electroacoustic transducer efficiency at the time of maximum rating output under the maximum state by controlling an output of a modulator for modulating a carrier by a sound signal so as to gradually increase it by a prescribed time constant. CONSTITUTION:An ultrasonic wave generator (e.g. a speaker) 2 is obtained by arranging 1000 ultrasonic wave oscillators 1 with 40kHz center frequency and connecting each 500 oscillators 1 in parallel as one channel. An output of a carrier oscillator 4 is modulated by an modulator 5 and inputted to an output controller 9. An output from the output controller 9 is amplified by a power amplifier 6 to drive the speaker 2. When a signal with a fixed amplitude is impressed to an input terminal of the output controller 9, its output signal voltage is gradually boosted with the passage of time. Consequently, driving point impedance also is gradually increased and the output power of the power amplifier 6 has flat characteristics. When the output is boosted up to the maximum rating in error simultaneously with power supply to the power amplifier 6, the amplifier 6 can be prevented from being broken.

IPC: B60L7/10
Filed: 1982-03-25
Abstract: PURPOSE:To improve the energy-saving and regenerating efficiency of an automatic train operation controller by regulating the power drive notch off speed in response to the voltage of a trolley wire in accordance with the pattern stored in advance. CONSTITUTION:A power drive notch off speed pattern memory/reader 5 outputs a power drive notch off speed pattern stored in advance for each station travel zone in response to a travel station zone signal from a travel station zone discriminator 4.

Abstract: PURPOSE:To obtain a diazo fixation type thermal recording medium having excellent chemical resistance, favorable raw preservability and high sensitivity, by providing on a photosensitive thermal recording layer a protective layer comprising a highly saponified polyvinyl alcohol having a saponification degree of at least a specified percent and a nonionic surfactant having an HLB of not less than a specified value. CONSTITUTION:A nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of not less than 10 is incorporated particularly in an amount of 3-0.1wt% based on the amount of a highly saponified polyvinyl alcohol having a saponification degree of not less than 95%. With the nonionic surfactant used, a uniform coated layer can be obtained, and even when a solid black image is formed, the density of the image is uniform, resolution is excellent, and an extremely favorable image can be obtained. If a so-called partially saponified polyvinyl alcohol having a saponification degree of less than 95% is used in a protective layer, raw preservability is degraded although chemical resistance is surely enhanced by the protective layer.

Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning device for collected water in which both maintenance of activity of aerobic bacteria in a cleaning part and control of increase in anaerobic bacteria in the case for unnecessitating cleaning of collected water are enabled by less suppressing power consumption. SOLUTION: When use and nonuse of the cleaning device are distinguished (S3) and it is distinguished that the cleaning device is not used, a pump for circulating collected water through a cleaning part is intermittently actuated (S10).
